文摘

CuCl32− ions could directly reduce Hg2+ to insoluble Hg0. CuCl32− ions play a catalytic role in the decomposition of Hg(SO3)22−. Low Cu2+ concentration could promote Hg0 re-emission due to the generation of Cu+. The Hg0 re-emission decreased due to the formation of metal Cu which could absorb Hg0 to form amalgam in high Cu2+ concentration. The addition of Cu ions change the electron transfer path of Hg(SO3)22−.
